Status LEWG with P0377
[ 2017-03-03, Kona, LEWG ]
Straw polls:
| constant | 3 |
| numeric_constant | 8 |
| static_constant | 1 |
| scalar_constant | 7 |
| integer_constant (Over LWG's dead body) | 1 |
| auto_constant | 4 |
| integral_c | 7 |
| int_ | 0 |
| | |
| scalar_constant | 6 |
| numeric_constant | 3 |
| integral_c | 5 |
Accept P0377 with "scalar_constant" for C++17 to address LWG 2922 and US 171:
SF | F | N | A | SA 0 | 1 | 3 | 7 | 5The *_constant<> templates (including the proposed addition, bool_constant<>) do not make use of the new template<auto> feature.
Proposed change: Add a constant<> (subject to bikeshedding) template which uses template<auto>.
Define integral_constant<> as using integral_constant<T, V> = constant<T(V)> or integral_constant<T, V> = constant<V>.
Either remove bool_constant, define it as using bool_constant = constant<bool(B)> or using bool_constant = constant<B>.
